<abstract><p>Recent years have been marked by a significant increase in interest in solving nonlinear equations that arise in various fields of natural science. This trend is associated with the creation of a new method of mathematical physics. The present study is devoted to the analysis of the propagation of $ m $-nonlinear viscoelastic waves equations in an unbounded domain. The physical properties are determined by the equations of the linear theory of viscoelasticity. This article shows the main effect and interaction between the different weak and strong damping terms on the behavior of solutions. We found, under a novel condition on the kernel functions, an energy decay rate by using an appropriate energy estimates.</p></abstract>

In this paper, we investigate a BVP for a class impulsive fractional partial differential equations. We propose a new topological approach to prove the existence of at least one classical solution and at least two nonnegative classical solutions. The arguments are based upon recent theoretical results.

To cope with the unauthorized access to the cloud treasure of resources and services, several cloud service providers implement the API-based access control approach and grant thus a full authentication of any client application. Once called, each cloud API (Application Programming Interface) is required to authenticate through a secret access key, commonly termed API key. A plethora of security risks is associated with these keys whether during their generation, storage, or utilization. The hardware secure element-based proposal aims for an end-to-end security between a cloud service provider and a client application. To ensure a reliable and secure API key exchange, the concerned entities rely on Public Key Infrastructure (PKI). As soon as an adversary acquires an unbounded computing power, it would be easy to intercept the keys and then unlock the gate behind the valuables over the cloud. In this paper, we propose a revised scheme that discards the PKI and installs a quantum mechanism to mutually authenticate the secure element and the cloud service provider by establishing a set of shared keys. A pioneering absolute security of the presented approach is warranted by the principles of quantum physics. To analyze the security of the quantum technology, we establish a formal verification based on PRISM model checking tool. We outstandingly focus on satisfying two prominent properties: (i) both the parties engaged in the quantum protocol are able to detect any disallowed eavesdropping and (ii) the valid amount of information caught by an adversary on the installed key must be negligible.

The study aimed at acknowledging the Six Sigma methodology and the existence of the essential components for the application, as well as reducing the time for completing the operations, reducing the error rate to the lowest possible level, and improving the quality of operations. For this objective, the analytical descriptive methodology was used on a sample consisted of 300 administrative and medical staff from Khartoum State Hospitals (Khartoum, Omdurman, Bahri). To this end, a questionnaire was used for collecting data and for analyzing it and achieving the results of the study by using the statistical analysis package (SPSS). The study deduced a number of results, the most important of which are that the items of commitment and supreme command support for the senior leadership and the methods of abundant human resources on quality control, and the application of the Six Sigma methodology in government hospitals in Khartoum state achieved a satisfactory level, while continuous improvement paragraphs, processes, and systems on quality control and the application of Six Sigma methodology achieved high quality. There is a significant effect on the extent of commitment and support of the higher leadership on quality control and the application of the Six Sigma methodology. Similarly, there is a statistically significant effect on the application of continuous improvement methods on quality control and Six Sigma methodology. Also, there is a statistically significant effect on the application of the abundance of human resources methods variable on quality control and the application of Six Sigma methodology in governmental hospitals in Khartoum state. The study recommended to take interest in the Six Sigma methodology and assure the possibility of using it in Khartoum State’s hospitals because of its scientific and practical importance in improving the quality of services and provided processes, and the need to provide qualified financial and human resources for using and developing Six Sigma methodology in hospitals, as well as great attention in training and providing departments heads with full knowledge of Six Sigma methodology and the fundamentals on which Six Sigma methodology, is based on its importance for hospitals. The study also recommended associating the promotions system in government hospitals in Khartoum state with the quality control program.

The purpose of this article is to present a method for assessing a short and open Arabic question during a learning activity. The proposed method is based on a combination of data presentation and a conceptual map of ontologies. The proposed method is based on the following steps: Process the text of the student's response by removing the stop words and sound from the text. Extract information about the student's response and plan in the form of a conceptual table; comparison between the reference and the student's response and assignment of points by semantic proportions; the score is calculated on the basis of the positional similarity of the measurement results.

The goal of this article is the development of an evaluation system based on the Arabic language. This article contains four parts. The first part is the corpus construction from the 7th year basic education classes' grammar book in Tunisia. Then, the second part is on the construction of the Concept Maps (CMaps) ontological for simple Arabic sentences from this corpus, where the automatic extraction of terms is completed. This extraction is based on two major approaches: linguistic and statistical. The third part in this article is the automatic instantiation. The last part is devoted to the application of the similarity measure chosen in the CMaps ontological fusion, which summarizes the various semantic links and which ends with a judgment according to the calculated score.

The evolutions of social Web and semantic Web lead us to ask ourselves about the way of supporting the personalization of learning by means of intelligent filtering of educational resources published in the digital networks. We recommend personalized courses of learning articulated around a first educational course defined upstream. Resuming the context and the stakes in the personalization, we also suggest anchoring the personalization of learning in a community of interest within a group of learners enrolled in the same training. This reflection is supported by the display of an active and semantic system of learning dedicated to the constitution of personalized to measure courses and in the due time.

Nevertheless the study level, the evaluation system used in the different Tunisian educational institutions, especially in the primary schools, raises several questions. Do these types of applications reveal the learners' cognitive metamorphoses? Do formative and summative evaluations aim to admit knowledge acquisition at the understanding expense? Is the subject matter of the evaluation instruments and approaches a vital part of the learners' earlier knowledge? Is there any link between the particular knowledge base of the learner and this content? Does the evaluation instruments system bring access to the construction of knowledge? Is this structure adapted to the evaluation of low-level cognitive skills better than to the assessment of high-level cognitive skills? Does the context of assessment establish influencing variables that may affect the learners' results? Do the used instruments frequently grant determining the learners' weaknesses and strengths? Do the correction norms comply with all the learner's answers estimated to enhance a special knowledge? Do objectivity necessities influence these characteristics more than the cognitive responses value? Actually, all of these questions reveal the importance and complexity of the evaluation problem in schools and also the learners' cognitive progress. They are completely connected to the content of the evaluation instruments and their form as well as their purposes and their backgrounds than to the correction criteria and norms. In this paper, we introduce a personalized evaluation environment for mobile learning. Firstly, we introduce an m-evaluation master plan. Then, we describe this personalization and the evaluation environment architecture consisting of Web services as well as based on communication between these services accomplished via Semantic web technologies. The environment presented authorizes evaluating the learners' knowledge of a particular teaching content by first of all searching, then selecting and finally generating a test perfectly suitable to their level of knowledge. Indeed, a new course will be proposed once the evaluation is achieved. We also handled an experimentation established to conclude the student's satisfaction degree.

The new form of education called "E-Learning" has grown significantly, especially in training institutions (Universities, Schools, Businesses, etc.). Consequently, they develop their software needs assessment in order to assess the information, and allow the learner to correct his knowledge autonomously. The teaching of languages takes place in the context of distance education and involves several research areas, as automatic processing of natural language and modeling of learning action in distance education environment. Therefore, the development of a remote Evaluation system for Arabic requires the preparation of various linguistic tools such as analyzers In this paper we focus on the development of a Morphological Analyzer In Arabic Language which can be operated in a remote evaluation system of the Arab that support during the seventh year basic level grammar taught in Tunisia. This work proposes to establish morphological analysis by promoting treatments that can be used by a system as the decomposition of a text, determining the properties of a word, the search in a text..., these treatments support learning through an explanation of ambiguous words, the integration strategies of Arabic grammar and solving exercises.
